This paper proposes an efficient technique for automatic localization of ear from side face images. The technique is rotation, scale and shape invariant and makes use of the connected components in a graph obtained from the edge map of the side face image. It has been evaluated on IIT Kanpur database consisting of 2672 side faces with variable sizes,(More)
Nodal explants excised from 18 to 20-year-old female plants of Simmondsia chinensis if cultured on Murashige and Skoog's medium supplemented with 20 μM N6-benzyladenine (BA) differentiated an average of 2.7 ± 0.4 shoots in 11.5% explants. The percentage of nodal explants inducing multiple shoots enhanced significantly if in vitro raised shoots were used as(More)
1.1 Origin The traveling salesman problem (TSP) were studied in the 18th century by a mathematician from Ireland named Sir William Rowam Hamilton and by the British mathematician named Thomas Penyngton Kirkman. Detailed discussion about the work of Hamilton & Kirkman can be seen from the book titled Graph Theory (Biggs et al. 1976). It is believed that the(More)
This paper presents an efficient ear recognition technique which derives benefits from the local features of the ear and attempt to handle the problems due to pose, poor contrast, change in illumination and lack of registration. It uses (1) three image enhancement techniques in parallel to neutralize the effect of poor contrast, noise and illumination, (2)(More)
This paper proposes an efficient skin-color and template based technique for automatic ear detection in a side face image. The technique first separates skin regions from nonskin regions and then searches for the ear within skin regions. Ear detection process involves three major steps. First, Skin Segmentation to eliminate all non-skin pixels from the(More)
The influence of different adjuvants, activated charcoal (AC), casein hydrolyzate (CH), coconut water (CW), polyvinylpyrrolidone (PVP), and triiodobenzoic acid (TIBA), has been assessed on the shoot production potential of the nodal explants derived from in vitro-raised male and female jojoba (Simmondsia chinensis) shoots. Nodal explants of each sex were(More)
This paper proposes an efficient indexing technique that can be used in an identification system with large multimodal biometric databases. The proposed technique is based on Kd-tree with feature level fusion which uses the multidimensional feature vector. A multi dimensional feature vector of each trait is first normalized and then, it is projected to a(More)
This paper proposes an efficient face recognition system which is invariant to pose. It presents a transformation to generate features of the frontal face from a given posed image of a subject. The proposed system has been tested on three databases viz. IITK, FERET and CMU-PIE. It has been observed that it performs better than the existing well known system.
